Unlike special relativity, Einstein's general relativity is an empirical concoction - a malleable combination of ad hoc equations and fudge factors allowing Einsteinians to predict anything they want. This means that general relativity has no postulates:

What are the postulates of General Relativity? Alexander Poltorak, Adjunct Professor of Physics at the CCNY: "In 2005 I started writing a paper, "The Four Cornerstones of General Relativity on which it doesn't Rest." Unfortunately, I never had a chance to finish it. The idea behind that unfinished article was this: there are four principles that are often described as "postulates" of General Relativity:

1. Principle of general relativity

2. Principle of general covariance

3. Equivalence principle

4. Mach principle

The truth is, however, that General Relativity is not really based on any of these "postulates" although, without a doubt, they played important heuristic roles in the development of the theory." [end of quotation]

Sometimes Einsteinians call Einstein's 1915 final ad hoc equations "postulates" (we all live in Einstein's schizophrenic world, don't we):

"Postulates of General Relativity

Postulate 1: A spacetime (M^4, g) is a Riemannian 4-manifold M^4 with a Lorentzian metric g.

Postulate 2: A test mass beginning at rest moves along a timelike geodesic. (Geodesic equation) ...

Postulate 3: Einstein equation is satisfied. (Einstein equation) ..." [end of quotation]
